Hi,

Can someone give me a general rule of how high to fill lead acid
batteries with distilled water?

I've seen sources that say to follow the battery makers
recommendations, or to look for the fill line.

Neither is available in my case.

I assume that I should fill them 1/2 inch to an inch above the plates?

Your wisdom is appreciated - and I'll pass it on.

Thanks,

Mike.
